Claims12
A device for securing a web end of a paper web in a paper making machine, the device comprising:
- a first drum;
- a second drum;
- a Pope roller disposed relative to the second drum so as to form a first nip there between, the first nip configured to pass the paper web;
- a second nip formed between the Pope roller and the first drum;
- a separator for severing the paper web so as to form the web end before the first nip, the web end being adhesive-free when it passes through the first nip;
- and
- at least one adhesive applicator positioned and configured to apply adhesive into a region adjacent the second nip, the region being located between the pope roller and the first drum in such a way that the adhesive is applied to a first area of the paper web and a second area of the paper web immediately covers the adhesive during winding of said first and second areas of the paper web onto the first drum, one of said first and second areas being the web end that is being secured to the first drum, the adhesive being applied by said adhesive applicator at a same time as the separator severs the paper web, the adhesive being located along the web end as the web end is wound onto the first drum such that the web end sticks to the first drum.
